JAMES B. ALLEN AND HARRY D. MORTON, OF DETROIT, MICHIGAN.

BINDING APPARATUS.

To all whom it may concern Be it known that we, JAMES B. ALLEN andHARRY- D. MORTON, citizens of the United States of America, residing atDetroit, in the county of lVayne and State of Michigan, have inventedcertain new and useful Improvements in Binding Apparatus, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

The invention relates to apparatus for threading flexible cords throughapertured bodies, being more particularly designed for use in connectionwith the binding of pamphlets.

In the present state of the art, pamphlets are frequently bound by loopsof cord passed through a series of apertures in the leaves and tied toform a bow-knot. This work is usually performed by hand and is a slowand tedious operation.

It is the object of the invention to provide means for threading thecords through the entire series of apertures in a single operation sothat the only hand work required is the tying of the bow.

It is a further object to associate this threading device with thepunching machine for forming the apertures so that the work deliveredfrom the punching device is in position for engagement with thethreading device.

In the drawings,Figure 1 is a section through the threading device; Fig.2 is a sectional perspective view showing one of the jaws of thethreading device; Fig. 3 is a section similar to Fig. 1 showing theparts in a difierent position; Fig. 4 is a perspective View of thecomplete work; Fig. 5 is a side elevation of the machine having apunching and threading device associated.

Generally described, the improved device comprises a channel memberadapted for registration with the apertured work to form a continuouspassage between a plurality of the apertures and pneumatic means forforcing the string or cord through said apertures and connectingchannel. Preferably the stringing is efl'ected by suction and bysimultaneously drawing in the opposite ends of the string or cord toform a loop.

In the specific construction shown, A is a suction head, B is a bed orsupport for the work which is provided with channels C therein forconnecting pairs of apertures through which the cord is to be looped.

Serial No. 699,621.

These channels C are preferably in the form eration the bed B ispreferably formed in H separable sections and the channels 0 are formedin the adjacent face of said sections so that when the latter areseparated the loop may be readily disengaged.

As shown in Fig. 2, the pamphlet to be bound is provided with threeapertures, the binding cord having its opposite ends drawn through theouter apertures and together passed through the central aperture. Thesupporting bed B is in the form of an angle guide upon which the openbook or pamphlet is placed, and the suction head is provided withcorresponding angling faces having a yieldable resilient gasket Dthereon which when pressed against the work upon the guide D will forman air tight joint.

gasket D as indicated at F, which prevents the accidental drawing of thecord completely through one of the apertures and into the suction head.

The supporting bed or guide member B has one of the sections thereoffixed while the other section is hinged and is movable preferably by afoot lever G and cooperating spring G into and out of contact with thefixed member. The same movement lowers the suction head and clamps thework previously registered with the channels in the guide. The work maybe fed into registration directly from the punching machine by providinga continuous guide H therebetween so that after the completion of thepunching operation the work may be slid along and into registration withthe channels in the guide. Thus one operator can punch the leaves andanother operator can thread the cords, the work being carried oncontinuously without interruption.

What we claim as our invention is:

1. The combination with a member having a channel therein forregistration with separate apertures in the work, of pneumatic means forstringing a cord through said apertures and connecting channel.

2. The combination with a channeled member having the opposite ends ofthe channel registerable with separate apertures in the work, of asuction head for covering one of said apertures to draw a string throughthe other aperture and connecting channel and out through the firstmentioned aperture.

3. The combination with a member having a channel therein, the oppositeends of which are registerable with separate apertures in the work, of apresser foot for holding the work in contact with said member, andsuction means carried by said foot registering with one of saidapertures.

4. The combination of a work support formed of separable members havinga channel formed in their adjacent faces, the ends of which areregisterable with separate apertures in the work, of pneumatic means forthreading the cord through one of said apertures and connecting channelout through the other aperture, when said sections of the work supportare together, the thread loop being detachable from said work supportupon the separation of the members thereof.

5. The combination of a work support in the form of a saddle comprisingtwo separable members having channeled adjacent faces with the ends ofthe channel registerable with separate apertures in the work, a movablehead for clamping the work upon said support, and pneumatic meanscarried by said head and registerable with one of the apertures in thework for threading a string through said apertures and connectingchannel.

6. The combination of a work support comprising a saddle formed ofmembers separable in the plane through the apex of said saddle andhaving their adjacent faces channeled to form a loop registerable withseparated apertures in the Work, a clamping head for the work upon saidsupport movable into and out of engagement therewith and having asuction head registerable with one of said apertures, means for movingsaid head, and co-acting means for separating the sections of said bedwhen said head is raised.

7. A work support having a plurality of loop channels therein forregistration with a plurality of separated apertures in the work andprovided with a common aperture therein, a work clamp having a suctionhead registerable with said common aperture and constituting a holderfor a loop of cord, said suction head being adapted to draw the oppositeends of the cord through said separated apertures, and connectingchannels into said common aperture and suction head in through saidseparated apertures and connecting channels into said common apertureand suction head.

In testimony whereof we affix our signatures in presence of twowitnesses.
